When running an APK that was compiled using Android Studio 3.4.1 with either the default version of R8 or with 1.5.30, I get the following error:

Verifier rejected class com.android.tools.r8.GeneratedOutlineSupport: org.geogebra.android.main.AppA_ com.android.tools.r8.GeneratedOutlineSupport.outline101(org.androidannotations.api.view.OnViewChangedListener) failed to verify: org.geogebra.android.main.AppA_ com.android.tools.r8.GeneratedOutlineSupport.outline101(org.androidannotations.api.view.OnViewChangedListener): [0x3] 'this' argument 'Reference: org.androidannotations.api.view.OnViewChangedListener' not instance of 'Reference: android.support.v4.app.Fragment' (declaration of 'com.android.tools.r8.GeneratedOutlineSupport' appears in /data/app/org.geogebra.android-wwf0YsE-c890aTz-5U3gTQ==/base.apk)

The class AppA is using the @EBean(scope=Ebean.Scope.Singleton) annotation, which generates a superclass containing

public static AppA_ getInstance_(Context context) {
if (instance_ == null) {
OnViewChangedNotifier previousNotifier = OnViewChangedNotifier.replaceNotifier(null);
instance_ = new AppA_(context.getApplicationContext());
instance_.init_();
OnViewChangedNotifier.replaceNotifier(previousNotifier);
}
return instance_;
}
You can see the code for OnViewChangeNotifier here: https://github.com/bobdeng/androidannotations/blob/master/AndroidAnnotations/androidannotations-core/androidannotations-api/src/main/java/org/androidannotations/api/view/OnViewChangedNotifier.java

This does not happen with Proguard. Unfortunatelly I can't share the whole project and I wasn't able to create a smaller example. I can share the .apk via email if it helps. Note that the project contains multiple classes with @EBean(scope=Ebean.Scope.Singleton), each of them has almost identical getInstance_ method.
